    The market diffusion of plug-in electric vehicles (PEVs) depends, besides many other factors, on how suitable these cars are for people's every day travel behavior. We combine the outcome of two model based approaches to derive how people's travel behavior might change if they use PEVs. The first model ALADIN determines the PEV owners, who are integrated within the second model, the microscopic travel demand simulation mobiTopp, in order to analyze the changes in travel behavior. The results show that PEVs in today's configuration are in many cases not suitable for daily mobility patterns and the mode has to be changed for some trips instead.

    Several attempts have been made in the literature to characterise the first users of electric vehicles. The approaches span from model-based assessments over techno-economical identification to survey. Here we compare EV user characterisations for Germany from several sources, including a model-based and a comprehensive EV user survey. Our results show already empirical sources can differ substantially but that model-based findings have to be analysed with care but can yield useful insights.
